The efficacies of two regimens for the treatment of acute clinical mastitis were compared in a randomised multi-centre field trial in Norway, using 657 cows. The purpose was to determine whether repeated intramuscular injections of penicillin G for three days were more effective than a single injection, when given in combination with intramammary treatment for five days. The results were evaluated on the basis of clinical and microbiological examinations and cell count determinations of quarter milk samples taken at the initial visit and four weeks later. There were no significant differences between the effects of the treatments, either for all the cows, or for subgroups of the cows based on age, stage of lactation, and systemic reaction, or the type of causal bacteria.
在挪威进行的一项随机多中心现场试验中，使用657头奶牛比较了两种治疗急性临床乳腺炎方案的疗效。目的是确定在与乳房内治疗五天联合使用时，连续三天肌肉注射青霉素G是否比单次注射更有效。根据首次就诊时和四周后采集的四分之一乳样的临床和微生物学检查以及细胞计数测定结果对结果进行评估。无论是对所有奶牛，还是对基于年龄、泌乳阶段、全身反应或致病细菌类型的奶牛亚组，治疗效果之间均无显著差异。
